Living Organisms and the Environment

abiotic factors - the non-living parts of an ecosystemExamples: water, sunlight, oxygen, temperature, soil

biotic factors - the living parts of an ecosystemExamples: people, animals, plants

population - the members of a single species in a given area. The area can be big or small - contained or not contained

Example: (contained) Texas prairie dog - prairie dog townExample: (not contained) finback whale - whole ocean

community - all populations that live together - They live close together and interact.Example: prairie dogs and quail

ecosystem - the combination of the community and abiotic factors

ecology - the study of how living things interact with each other and their environment
